Am I likely to become pregnant if I took emergency contraception 29 hours after being raped? #305/14

I was raped on the first of March.  I used the emergency contraceptive, Postinor (Postinor in Europe is the same as Plan B in the United States),  29 hours later.  Am I likely to become pregnant?

Good morning



I am so sorry you have been forced to deal with two different issues, rape and the risk for an unwanted pregnancy.  You seem to have responded very quickly.  Good job.


Your pregnancy test will now be positive if you are pregnant, BUT YOU MOST LIKELY ARE NOT PREGNANT.

Where do you stand today?
